Progress in Essential Oils: Long Pepper Oil

The present article is a survey of literature evaluating the constituents of Piper longum L., or long pepper, fruit oil. In one case, early researchers found the oil was devoid of monoterpene compounds and rich in sesquiterpenes, with b-caryophyllene being the major hydrocarbon. Lawrence (1978) and others also examined the composition of P. longum, the findings from which are discussed here.

It has been preserved thanks to age-old traditions, to strict observation of the technology, persistent and careful quality control, the Government’s concern and the extremely high international praise for the oil.

The history of lavender oil: Disturbing inferences for the future of essential oils

Whether the user industries will think it worth supporting the production of pure essential oils, this writer cannot tell. Where new sources are concerned it will involve taking up the limited output of the early years while the project grows. But if every user leaves this for someone else to do, it is not difficult to predict the degradation and disappearance of oils that are as good and plentiful today as true lavender was fifty years ago.

Essential Oil of Heterotheca Latifolia

Although there are several papers in the bibliography about this genus, no one has studied or described its aroma. We have identified in a previous work the main constituents of the essential oil from its aereal parts and showed an olfactive evaluation that was further confirmed by the assistance of the Symposium of Natural Aromatic and Medicinal Resources, held in Necochea, Argentina in 1984. The confirmation of those compounds and identification of some others present in minor quantities are given in this paper. Furthermore, we present a critical analysis of the potential economic value of this essence for the fragrance industry.
